Energy Storage in Underwater Balloons

Tom Lombardo for  Grid-level energy storage takes many forms, including flow batteries, Li-ion batteries, pumped hydro, compressed air in underground caverns, and even flywheels. Toronto’s Hydrostor just added another tool to the arsenal: underwater compressed air energy storage (UCAES). Hydrostor recently activated a pilot UCAES plant - the first of its kind - that will provide grid-level storage for the city of Toronto. In addition to supplying the city with cost-effective energy storage, the system will allow engineers to study its behavior and optimize the design. Can UCAES become a viable energy storage technology?
The idea has been around for many years: when supply exceeds demand, use the excess energy to run an air compressor and store the air in an underwater balloon. When power is needed, open a valve and let the compressed air run a turbine to generate electricity. The principle is simple, but the economic feasibility has yet to be demonstrated. Hydrostor hopes that their facility becomes the proving ground.  Cont'd...

Trina Solar to Supply 96.2 MW of Solar Modules to the Largest Solar Project in Kyushu, Japan

The project is expected to commence commercial operations in the spring of 2018 and generate clean energy for up to 30,000 households, delivering annual CO2 emission savings of 68,200 tons compared with coal-generated power.

36 countries launch world alliance for geothermal energy

Thirty-six countries gave the official start Monday to an initiative to promote geothermal energy in developing economies as a cleaner alternative to oil, gas and coal.

The Global Geothermal Alliance, launched on the sidelines of the UN climate talks in Le Bourget, aims at a sixfold increase in geothermal electricity production and a tripling of geothermal-derived heating by 2030.

At present, geothermal is growing modestly, at three to four percent per year, providing 12 gigawatts of electricity annually.

But this is just a fraction of its overall potential of 100 gigawatts, according to the industry. Only 24 out of 90 countries with geothermal potential actually use the resource.

The alliance said its members will seek to overcome "political uncertainty" about geothermal and strengthen the industry's skills base.

The Global Geothermal Alliance initiative was sketched out in September 2014 at a summit organised by UN Secretary General Ban Ki-moon.

Members include countries on thermal "hotspots" in Africa, Southeast Asia and Latin America, ranging from Kenya and Tanzania to Malaysia, the Philippines and Guatemala.  Cont'd...

New Global Solar Council Launches out of COP21

The UN COP21 climate talks are the most comprehensive thus far and are showing that countries actually are preparing to and are taking action on climate change. The solar industry is posed to be part of the answer and as is increasingly working together to do so. Yesterday (Dec. 7) at the conference the industry announced the Global Solar Council (GSC) in an attempt to share best practices and bring the solar power industry together at an international level.
